FIG. 2 is an exploded perspective view of a planar antenna, and FIG. 3 is an explanatory diagram for explaining an assembly process. The overall configuration will be described with reference to FIG. In FIG. 1A, a planar antenna 10 as an antenna device is configured as follows. On the box-shaped base 11, the plate-like first laminated member 12, the second laminated member 13, the third laminated member 14, and the plate-like antenna constituting member 19 are elastically deformed into a flat plate shape. The elastic plate members 15 are stacked in close contact with each other. Each of the first laminated member 12, the second laminated member 13, the third laminated member 14, and the end portions 15a (details will be described later) of the elastic plate 15 as a pressing plate elastically deformed into a flat plate shape have almost the entire length. In addition, it is crimped by a fixing member bent in an L shape, a crimping member, and a crimping member 18 (detailed later) as a locking member, and is fixed integrally to the base 11. The elastic plate 15 has a partial cylindrical shape with a radius of curvature R as shown in FIG. 1B until it is flattened (details will be described later). The elastic plate member 15 has a large number of openings 15d for radiating radio waves, and the surface of the elastic plate member 15 constitutes the antenna opening surface 10a.

次に、個別の部品の詳細を図２により説明する。ベース１１は、図２（ｃ）に示すように、底板のない箱状の形状を有しており、その上面の左右両側に板部材１７が対向配置され固定されている。板部材１７は、組み立て前は断面が長方形である。第１の積層部材１２、第２の積層部材１３、第３の積層部材１４は、図２（ｂ）に示すように、それぞれ長方形の薄い平板状の形状を有し、細長い複数のスリット１２ｆ，１３ｆ，１４ｆが形成されており、第１の積層部材１２、第２の積層部材１３、第３の積層部材１４を積層したときこれらスリット１２ｆ，１３ｆ，１４ｆが積層方向から見て同じ位置に位置し、積層方向に電波が通過する導波管路を形成している。第１の積層部材１２、第２の積層部材１３、第３の積層部材１４は、例えばステンレス板やアルミニューム板にて製作される。   Next, details of the individual components will be described with reference to FIG. As shown in FIG. 2C, the base 11 has a box-like shape without a bottom plate, and plate members 17 are arranged oppositely and fixed on the left and right sides of the upper surface. The plate member 17 has a rectangular cross section before assembly. As shown in FIG. 2B, each of the first laminated member 12, the second laminated member 13, and the third laminated member 14 has a rectangular thin flat plate shape, and includes a plurality of elongated slits 12f, 13f and 14f are formed, and when the first laminated member 12, the second laminated member 13, and the third laminated member 14 are laminated, the slits 12f, 13f, and 14f are located at the same position when viewed from the lamination direction. In addition, a waveguide path through which radio waves pass in the stacking direction is formed. The first laminated member 12, the second laminated member 13, and the third laminated member 14 are made of, for example, a stainless steel plate or an aluminum plate.

弾性板材１５は、組み立て前は図２（ａ）に示すように、所定の弾性を有する板状の弾性材料で図２（ａ）における上方向にのみ曲率を持つ曲板この例では後述の式（１）を満たす曲率を有する部分円筒状の曲板に形成されており、図２（ａ）における左右方向に対向する円周方向の一対の端部である直線状の端部１５ａと、図２（ａ）における奥行き方向に対向する軸方向の端部である部分円筒状の端部１５ｂを有する。弾性板材１５は、例えば、ばね用ステンレス鋼帯（ＳＵＳ３０１−ＣＳＰ、ＳＵＳ３０４−ＣＳＰ：ＪＩＳ Ｇ ４３１３：１９９６など）で製作する。このような弾性板材１５の両方の端部１５ａが加締め部材１８（図１（ａ）参照、詳細後述）により押さえられて弾性変形して図１（ａ）に示すようにほぼ平板状になり、そのばね力により第３の積層部材１４、第２の積層部材１３、第１の積層部材１２をほぼその全面に亘ってベース１１に押圧した状態で固定されている。   As shown in FIG. 2A, the elastic plate 15 is a plate-like elastic material having a predetermined elasticity, and has a curvature only in the upward direction in FIG. 2A. A linear end portion 15a, which is a pair of circumferential end portions that are formed in a partially cylindrical curved plate having a curvature satisfying (1) and opposes in the left-right direction in FIG. 2 (a) has a partially cylindrical end portion 15b which is an end portion in the axial direction opposed to the depth direction. The elastic plate member 15 is made of, for example, a stainless steel band for spring (SUS301-CSP, SUS304-CSP: JIS G 4313: 1996, etc.). Both ends 15a of such an elastic plate member 15 are pressed and elastically deformed by a caulking member 18 (see FIG. 1 (a), details will be described later) to become substantially flat as shown in FIG. 1 (a). The third laminated member 14, the second laminated member 13, and the first laminated member 12 are fixed to the base 11 almost over the entire surface by the spring force.

このような平面アンテナ１０の組み立て順序を、図３により説明する。組み立てには、加締め治具１０１を用いるが、加締め治具１０１は図３（ａ）に示すように図の左右に当接部１０１ａ、溝形成部１０１ｂ及び肩部１０１ｃをそれぞれ有する。溝形成部１０１ｂは、当接部１０１ａから所定の深さの溝１０１ｄを形成しており、板部材１７と嵌合するようにされている。組み立ては、予めベース１１に固定された板部材１７に合わせてベース１１の上に第１の積層部材１２、第２の積層部材１３、第３の積層部材１４を順に積み重ね、図３（ｃ）の状態とする。このとき、各スリット１２ｆ，１３ｆ，１４ｆの積層方向の位置を合わせる。   The assembly order of such a planar antenna 10 will be described with reference to FIG. For the assembly, a caulking jig 101 is used, and the caulking jig 101 has a contact portion 101a, a groove forming portion 101b, and a shoulder portion 101c on the left and right sides of the drawing as shown in FIG. The groove forming part 101 b forms a groove 101 d having a predetermined depth from the contact part 101 a and is adapted to be fitted to the plate member 17. Assembling, the first laminated member 12, the second laminated member 13, and the third laminated member 14 are sequentially stacked on the base 11 in accordance with the plate member 17 fixed to the base 11 in advance, and FIG. State. At this time, the positions of the slits 12f, 13f, and 14f in the stacking direction are matched.

第３の積層部材１４の上に弾性板材１５（図３（ｂ））を下に凸の状態にして乗せる。以上がこの発明における押圧板配設工程である。その上から加締め治具１０１（図３（ａ））を当て、その溝形成部１０１ｂを加締め部材１８に嵌合させ、当接部１０１ａがベース１１に当接するまで押し下げる（この工程がこの発明における治具押圧工程である）。このとき、弾性板材１５はその端部１５ａが押し下げられてほぼ平板状になるとともに、板部材１７は加締め治具１０１の肩部１０１ｃ（図３（ａ））により内側に折り曲げられて逆Ｌ状の形状に塑性変形して加締め部材１８となり、弾性板材１５の端部１５ａを含めた第１の積層部材１２、第３の積層部材１４の端部を加締める形で固定する。以上がこの発明における押圧板固定工程である。すなわち、板状のアンテナ構成部材１９をベース１１との間に挟むようにして弾性板材１５を配設し、弾性板材１５の端部１５ａをほぼその全長に亘って押圧し固定する。第１の積層部材１２、第２の積層部材１３、第３の積層部材１４は、弾性板材１５のばね力によりベース１１に押し付けられた状態で固定され、図１に示す平面アンテナ１０が製作される。   An elastic plate 15 (FIG. 3B) is placed on the third laminated member 14 so as to protrude downward. The above is the pressing plate disposing step in the present invention. The caulking jig 101 (FIG. 3A) is applied from above, and the groove forming portion 101b is fitted to the caulking member 18, and is pushed down until the abutting portion 101a abuts on the base 11 (this process is this process). This is a jig pressing step in the invention). At this time, the end portion 15a of the elastic plate 15 is pushed down to be substantially flat, and the plate member 17 is bent inward by the shoulder portion 101c (FIG. 3A) of the caulking jig 101 to reverse L. The ends of the first laminated member 12 and the third laminated member 14 including the end 15a of the elastic plate 15 are fixed by crimping. The above is the pressing plate fixing step in the present invention. That is, the elastic plate member 15 is disposed so as to sandwich the plate-like antenna component member 19 between the base member 11 and the end portion 15a of the elastic plate member 15 is pressed and fixed over substantially the entire length. The first laminated member 12, the second laminated member 13, and the third laminated member 14 are fixed in a state of being pressed against the base 11 by the spring force of the elastic plate 15, and the planar antenna 10 shown in FIG. The

ここに、弾性板材１５は、一方向にのみ曲率を持つ曲板であり、その曲面を例えば次の式（１）を満たすように形成する。

(1)
Where Y: deflection amount,
X: position in the direction connecting two fixed points of the plate-like member,
Ymax: maximum deflection,
L: Fixed point interval of the plate-like member.

また、弾性板材１５の押圧により発生する接触面圧を等分布とするために、対向する円周方向の端部である端部１５ａを、加締め部材１８にて固定し、１辺当たりの固定力Ｆを次の式（２）で表される力以下とする。
Ｆ＝１９２Ｅｂｈ＾３Ｙｍａｘ／（６０Ｌ＾３） ・・（２）
ここに、Ｅ：板材の縦弾性係数、
ｂ：弾性板材端部の曲率を持たない辺の長さ、
ｈ：弾性板材の厚み、
Ｙｍａｘ：最大たわみ量（上述）、
Ｌ：板状部材の固定点間隔（上述）。 Further, in order to make the contact surface pressure generated by the pressing of the elastic plate 15 evenly distributed, the end portions 15a which are opposite ends in the circumferential direction are fixed by the caulking member 18 and fixed per side. The force F is set to be equal to or less than the force represented by the following expression (2).
F = 192Ebh ^ 3Ymax / (60L ^ 3) (2)
Where E: longitudinal elastic modulus of the plate material,

弾性板材１５及び第１の積層部材１２〜第３の積層部材１４を、ベース１１に組付後、アンテナ開口面１０ａの励振位相を均一に保つために、弾性板材１５が平面状に保持（維持）される必要がある。そのために、ベース１１は弾性板材１５に対して断面係数が充分に高いものとなるように、箱形の形状を有するものとしている。なお、ベース１１の代わりに厚板状のベースを使用したり、弾性板材１５と同じ材料を用いた場合は、弾性板材１５よりもベース１１の板厚を充分に厚くしたりして、充分な剛性を確保する。また、弾性板材１５とベース１１の板厚とを同じ厚さにする必要がある場合は、弾性板材１５よりもベース１１の弾性係数が高い強い材料を選定する。   After the elastic plate member 15 and the first laminated member 12 to the third laminated member 14 are assembled to the base 11, the elastic plate member 15 is held (maintained) in a flat shape in order to keep the excitation phase of the antenna opening surface 10a uniform. ) Need to be done. Therefore, the base 11 has a box shape so that the section modulus of the elastic plate 15 is sufficiently high. If a thick plate-like base is used in place of the base 11 or the same material as the elastic plate material 15 is used, the thickness of the base 11 is made sufficiently thicker than the elastic plate material 15, and sufficient Ensure rigidity. Further, when it is necessary to make the plate thickness of the elastic plate member 15 and the base 11 the same, a strong material having a higher elastic coefficient of the base 11 than the elastic plate member 15 is selected.

なお、上記では固定部材としての加締め部材１８により、第１〜第３の積層部材１２〜１４及び弾性板材１５をベース１１との間で加締めるものを示したが、これに限られるものではなく、例えば次のようにして固定することもできる。加締め部材１８の代わりに最初からＬ状に加工された固定部材としての係止部材を用意する。ベース１１上に第１〜第３の積層部材１２〜１４を積層し、この上に弾性板材１５を上述したのと同じ要領で載せ、上記加締め治具１０１と類似（加締めの機能は不要）の押さえ治具を用いて弾性板材１５の端部１５ａを押さえつけ、ほぼ平板状する。この平板状になった状態の弾性板材１５の端部１５ａを、上記係止部材にて係止する。この場合、係止部材はベース１１に例えば接着剤にて接着する。   In the above description, the caulking member 18 as a fixing member is used to caulk the first to third laminated members 12 to 14 and the elastic plate member 15 between the base 11, but the present invention is not limited to this. For example, it can also be fixed as follows. Instead of the caulking member 18, a locking member is prepared as a fixing member processed into an L shape from the beginning. The first to third laminated members 12 to 14 are laminated on the base 11, and the elastic plate member 15 is mounted thereon in the same manner as described above, and is similar to the crimping jig 101 (the caulking function is unnecessary). ) Is used to press the end 15a of the elastic plate 15 so that it is substantially flat. The end 15a of the elastic plate 15 in a flat plate shape is locked by the locking member. In this case, the locking member is bonded to the base 11 with an adhesive, for example.

以上のように、この実施の形態においては、固定後、第１の積層部材１２、第２の積層部材１３、第３の積層部材１４間の面圧が均一になるように固定する必要があるため、加締め時に、弾性板材１５や第１の積層部材１２〜第３の積層部材１４に過大な力を加えることなく固定できる加締め治具１０１を用いた。図３（ｄ）に示すように、加締め治具１０１は、押圧した弾性板材１５が、ベース１１側に押し付けられ、ほぼ平板状となった状態で加締め治具１０１の当接部１０１ａがベース１１に当たり止まるようなものとした。図１（ａ）に示すように、板部材１７を折り曲げ加締め固定後は、最上部の弾性板材１５が弾性変形してほぼ平板状となっているため、そのばね力（復元力）により、第１の積層部材１２〜第３の積層部材１４がほぼ全面に亘ってベース１１に押し付けられた状態となる。   As described above, in this embodiment, after the fixing, it is necessary to fix the first laminated member 12, the second laminated member 13, and the third laminated member 14 so that the surface pressure is uniform. Therefore, the caulking jig 101 that can be fixed without applying excessive force to the elastic plate member 15 and the first laminated member 12 to the third laminated member 14 during caulking is used. As shown in FIG. 3D, the caulking jig 101 has an abutting portion 101a of the caulking jig 101 in a state where the pressed elastic plate member 15 is pressed to the base 11 side and becomes substantially flat. It was supposed to hit the base 11. As shown in FIG. 1 (a), after the plate member 17 is bent and caulked and fixed, the uppermost elastic plate member 15 is elastically deformed and has a substantially flat plate shape. Therefore, due to its spring force (restoring force), The first laminated member 12 to the third laminated member 14 are pressed against the base 11 over almost the entire surface.

そして、少ない構成部品で導波路やアンテナ開口面を直線状に隙間なく保持できることから、導波路やアンテナ開口面で励振位相の均一化が可能である。従って、第１の積層部材１２〜第３の積層部材１４に振動衝撃が作用し、あるいは大幅な温度変化がある環境においても、第１の積層部材１２〜第３の積層部材１４同士の密着を保つことができる。このように、簡易な構成でアンテナ構成部材を固定することができる。従って、部品点数を削減でき、製作の容易な平面アンテナを得ることができる。また、上述したような製造方法によれば、部品点数を削減でき、製作の容易な平面アンテナの製造方法を提供することができる。   Since the waveguide and the antenna opening surface can be held linearly without gaps with a small number of components, the excitation phase can be made uniform on the waveguide and the antenna opening surface. Therefore, the first laminated member 12 to the third laminated member 14 are brought into close contact with each other even in an environment where a vibration impact acts on the first laminated member 12 to the third laminated member 14 or there is a significant temperature change. Can keep. Thus, the antenna component can be fixed with a simple configuration. Therefore, the number of parts can be reduced, and an easily manufactured planar antenna can be obtained. Moreover, according to the manufacturing method as described above, the number of components can be reduced, and a method for manufacturing a planar antenna that can be easily manufactured can be provided.

Thereafter, the pressing jig 102 (FIG. 4A) is pressed against the base 21 side (FIG. 4D) until the uppermost elastic plate 15 becomes flat. In this state, the end 15a of the elastic plate 15 and the ends of the first laminated member 12 to the third laminated member 14 are melted over the entire surface of the end of the base 21 to form the end welded portion 20a to be welded and fixed. To do. In addition to the joining by welding as described above, joining may be performed by welding using a laser or the like, brazing or soldering. FIG. 5 shows a state of the planar antenna 20 as the antenna device after welding and fixing.

また、変形例として、図６に示すようには、ベース２１の端部の一部と第１の積層部材１２〜第３の積層部材１４の端部と弾性板材１５の端部１５ａとを溶着して端部溶着部３０ａを形成して一体化して、アンテナ装置としての平面アンテナ３０とすることもできる。この実施の形態における平面アンテナ２０，３０においても、固定後は、実施の形態１と同様、弾性板材１５の弾性力により、第１の積層部材１２〜第３の積層部材１４が、ほぼ全面に亘ってベース２１に押し付けられた状態となるため、第１の積層部材１２〜第３の積層部材１４に振動衝撃が作用し、あるいは大きな温度変化がある環境においても、ベース２１及び第１の積層部材１２〜第３の積層部材１４同士の密着を保つことができる。従って、部品点数を削減でき、製作の容易な平面アンテナを得ることができる。   As a modification, as shown in FIG. 6, a part of the end of the base 21, the ends of the first laminated member 12 to the third laminated member 14, and the end 15 a of the elastic plate 15 are welded. Then, the end welded portion 30a can be formed and integrated to form a planar antenna 30 as an antenna device. Also in the planar antennas 20 and 30 in this embodiment, after fixing, the first laminated member 12 to the third laminated member 14 are almost entirely covered by the elastic force of the elastic plate member 15 as in the first embodiment. The base 21 and the first laminated member 12 are pressed against the base 21 so that vibration impact acts on the first laminated member 12 to the third laminated member 14 or there is a large temperature change. The adhesion between the members 12 to the third laminated member 14 can be maintained. Therefore, the number of parts can be reduced, and an easily manufactured planar antenna can be obtained.

FIGS. 9 and 10 show the fourth embodiment, FIG. 9 is an explanatory view showing a manufacturing process of the planar antenna, and FIG. 10 is a perspective view showing the planar antenna manufactured by the manufacturing method of FIG. . As shown in FIG. 9C, the lower end 46a is bent and fixed using a fixing member having a slit forming portion 46c that forms a slit 46b in the upper portion and a locking member 46 as a locking member. You can also. In the planar antenna 50 as the antenna device, first, the first laminated member 12 to the third laminated member 14 are laminated on the base 21 (FIG. 9C), and an elastic plate member 45 (elastic plate member 45 ( FIG. 9B is placed. In this case, the elastic plate member 45 is the same as the elastic plate member 15 shown in FIG. 1, but the length of the end portions 45a which are a pair of end portions in the left-right direction, ie, the circumferential direction in FIG. This is for engaging a slit forming portion 46c of a locking member 46 described later.

弾性板材４５を第３の積層部材１４の上に置いた後、押さえ治具１０２（図９（ａ））にて最上部の弾性板材４５が平面状になるまでベース２１側に押し付けた状態（図９（ｄ））とし、ベース２１の端部に係止部材４６の端部４６ａを係合させ、同時に平板状に押さえられた弾性板材４５の端部４５ａに係止部材４６のスリット形成部４６ｃを嵌合させ、第１の積層部材１２〜弾性板材４５をベース２１に固定する。図１０に、このようにして製作された平面アンテナ５０を示す。   After the elastic plate member 45 is placed on the third laminated member 14, the pressing jig 102 (FIG. 9A) presses the elastic plate member 45 toward the base 21 until the uppermost elastic plate member 45 becomes flat ( 9 (d)), the end portion 46a of the locking member 46 is engaged with the end portion of the base 21, and at the same time, the slit forming portion of the locking member 46 is engaged with the end portion 45a of the elastic plate 45 that is pressed flat. 46 c is fitted, and the first laminated member 12 to the elastic plate member 45 are fixed to the base 21.

実施の形態５．
図１１、図１２は、実施の形態５を示すものであり、図１１は平面アンテナの製作工程を示す説明図、図１２は平面アンテナを示す斜視図である。この実施の形態においては、ベース６１及び固定部材及び係止部材としての固定枠６６の構成が上記各実施の形態とは異なる。ベース６１は、図１１（ｄ）に示すように、蓋無しの箱を天地逆にしたような形状を有する点は実施の形態１の図２（ｃ）におけるベース１１と同様であるが、左右の両端部近傍にそれぞれ２箇所、嵌合穴形成部６１ａにより嵌合穴６１ｂが形成されている点が異なる。 Embodiment 5 FIG.
FIGS. 11 and 12 show the fifth embodiment, FIG. 11 is an explanatory view showing a manufacturing process of a planar antenna, and FIG. 12 is a perspective view showing the planar antenna. In this embodiment, the structure of the base 61, the fixing member, and the fixing frame 66 as the locking member is different from those of the above-described embodiments. As shown in FIG. 11 (d), the base 61 is similar to the base 11 in FIG. 2 (c) of the first embodiment in that the box without a lid is shaped upside down. The difference is that two fitting holes 61b are formed by fitting hole forming portions 61a in the vicinity of both end portions of each.

また、固定枠６６は、図１１（ａ）に示すように、押さえ部６６ａ、連結部６６ｂ、嵌合ピン６６ｄを有する。左右一対の押さえ部６６ａは、Ｌ状に形成され、一対の連結部６６ｂは一対の押さえ部６６ａを押さえ部６６ａの長さ方向（図１１（ａ）における奥行き方向）の端部において連結して四角形の枠状を成している。嵌合ピン６６ｄが、各押さえ部６６ａの底部の２箇所に形成された図示しない穴に一方の端部が圧入され締まり嵌め状態で嵌合されている。また、嵌合ピン６６ｄの他方すなわち下方の端部は、テーパ状に加工されている。   Further, as shown in FIG. 11A, the fixed frame 66 includes a pressing portion 66a, a connecting portion 66b, and a fitting pin 66d. The pair of left and right pressing portions 66a are formed in an L shape, and the pair of connecting portions 66b connect the pair of pressing portions 66a at the end portions in the length direction of the pressing portion 66a (the depth direction in FIG. 11A). It has a rectangular frame shape. One end of the fitting pin 66d is press-fitted into a hole (not shown) formed at two locations on the bottom of each pressing portion 66a and is fitted in an interference fit state. The other end of the fitting pin 66d, that is, the lower end is processed into a tapered shape.

アンテナ装置としての平面アンテナ６０は、実施の形態１と同様、まずベース６１上に第１の積層部材１２〜第３の積層部材１４（図１１（ｃ））を積層し、その上に弾性板材１５（図１１（ｂ））を置き、さらにその上に固定枠６６を置く。固定枠６６を置くとき、その嵌合ピン６６ｄの位置をベース６１の嵌合穴６１ｂの位置に合わせる。その後、図７の押さえ治具１０２と同様の押さえ治具にて最上部の固定枠６６を介して弾性板材１５が平面状になるまでベース６１（図１１（ｄ））側に押し付けた状態とし、同時に嵌合ピン６６ｄをベース６１の嵌合穴６１ｂに圧入し嵌合穴形成部６１ａと締まり嵌め状態で嵌合させる。   As in the first embodiment, the planar antenna 60 as the antenna device is formed by first laminating the first laminated member 12 to the third laminated member 14 (FIG. 11C) on the base 61, and then elastic plate material thereon. 15 (FIG. 11B) is placed, and a fixed frame 66 is placed thereon. When the fixing frame 66 is placed, the position of the fitting pin 66d is matched with the position of the fitting hole 61b of the base 61. After that, a pressing jig similar to the pressing jig 102 in FIG. 7 is pressed against the base 61 (FIG. 11 (d)) until the elastic plate 15 is flattened through the uppermost fixed frame 66. At the same time, the fitting pin 66d is press-fitted into the fitting hole 61b of the base 61 and is fitted to the fitting hole forming portion 61a in an interference fit state.

これにより、箱状のベース６１の上に、アンテナ構成部材１９としての第１の積層部材１２と第２の積層部材１３と第３の積層部材１４及び弾性板材１５が互いに密着して積層され、弾性変形した弾性板材１５の弾性力により第１の積層部材１２及び第２の積層部材１３並びに第３の積層部材１４がほぼ全面に亘ってベース１１に押圧されている。   Thereby, on the box-shaped base 61, the first laminated member 12, the second laminated member 13, the third laminated member 14, and the elastic plate 15 as the antenna component member 19 are laminated in close contact with each other, The first laminated member 12, the second laminated member 13, and the third laminated member 14 are pressed against the base 11 over almost the entire surface by the elastic force of the elastic plate member 15 that has been elastically deformed.

このとき、固定枠６６にて第１の積層部材１２〜第３の積層部材１４及び弾性板材１５を確実に押圧するために、押さえ部６６ａの垂直の高さ（図１１（ａ）の上下方向寸法）を第１の積層部材１２〜第３の積層部材１４及び弾性板材１５の合計厚さよりも若干短くしておく。このように短くしておけば、押さえ部６６ａを充分に押し下げて第１の積層部材１２〜第３の積層部材１４及び弾性板材１５の端部を確実に押圧した状態で嵌合ピン６６ｄと嵌合穴形成部６１ａとが嵌合するので、確実に第１の積層部材１２〜第３の積層部材１４及び弾性板材１５をベース６１に固定できる。このようにして製作された平面アンテナ６０を図１２に示す。   At this time, in order to reliably press the first laminated member 12 to the third laminated member 14 and the elastic plate member 15 with the fixed frame 66, the vertical height of the pressing portion 66a (the vertical direction in FIG. 11A). The dimension) is slightly shorter than the total thickness of the first laminated member 12 to the third laminated member 14 and the elastic plate member 15. If shortened in this way, the pressing portion 66a is sufficiently pushed down so that the end of the first laminated member 12 to the third laminated member 14 and the elastic plate member 15 is securely pressed and fitted with the fitting pin 66d. Since the fitting hole forming portion 61 a is fitted, the first laminated member 12 to the third laminated member 14 and the elastic plate member 15 can be reliably fixed to the base 61. A planar antenna 60 manufactured in this way is shown in FIG.

なお、上記では嵌合ピンを固定枠に嵌合穴をベースに設けた例を示したが、これを逆にして嵌合ピンをベースに固定枠に嵌合穴を設けてもよい。   In the above description, the fitting pin is provided in the fixed frame and the fitting hole is provided in the base. However, the fitting pin may be provided in the fixing frame and the fitting hole may be provided in the fixing frame.

Has been. That is, the elastic plate member 75 is formed in a partial spherical shape having curvatures in the x direction and the y direction in x, y, z three-dimensional coordinates, and ends 75a in the x direction as a pair of ends on the short side, It has the edge part 75b of the y direction which is the long side orthogonal to this edge part 75a of this short side. The elastic plate 75 is made of, for example, a spring stainless steel strip similar to the elastic plate 15 of FIG. Such an elastic plate member 75 is used in place of the elastic plate member 15 shown in FIGS. 1, 3, 4, 7, 11 and the like.
